Invalid Steam UserID Ticket

[[EA]]

Getting 'Invalid Steam UserID Ticket' message?
This is a common issue after Valve's changes to 2007 SDK.
- Shut your Steam down;
- Delete Steam\config\config.vdf and Steam\clientregistry.blob files;
- Start Steam again, it will recreate the deleted files and the problem should be gone.

Just stealing this for the thread cobra for those who have the problem (aka half the people playing).

does not work.

Hmmm... I'll ask Source Jesus.

TPD_-> IF you have the "invalid steam ticket" error try delete app AppUpdateStats.blob and ClientRegistry.blob in the steam folder and config.vdf ( optional ) in the steam/config folder and then restart steam

if above doesnt work for a hard fix delete everything except Steam.exe and /steamapps in /Steam ( will destroy a lot of your steam settings ) -> be sure to make a backup
